Abstract


Large wind farms into the weak centralized power grid has changed the trend of the original distribution voltage levels and system inertia , etc., to give greater impact grid stability . With wind power capacity increases , wind power systems containing large disturbance stability analysis of wind power has become one of the hotspots . In this paper, Inner Mongolia Power Dispatching and Communication Center \In this paper are as follows: First, create electromechanical transient simulation for wind turbine model ; achieved with wind power flow calculation and electromechanical transient simulation ; verify the accuracy of the model wind unit equivalents ; analysis of wind speed , fault wind farm transient stability . Then , analyze a large number of wind power into the grid Inner Mongolia Power Grid Transient Stability. The use of \voltage transient Stability . And verify that the Inner Mongolia Power Grid communications dispatch center technology projects \Then, the proposed wind farm from the grid point of the low voltage ride through capability optimized design proposal. Papers from our national conditions , analysis of the impact of low-voltage ride-through capability factors ; gives a low voltage ride through characteristic design elements and calculation methods , and gives an example of Inner Mongolia DEFINITION regional grid wind farm in the region of low voltage ride through ability to optimize the design. Finally, the study of the use of FACTS devices to improve transient characteristics of the wind farm approach , and two kinds of SVC and STATCOM compensation Containing Wind Power System Transient Stability improved simulation comparison results show that the use of STATCOM can be better to improve the system transient stability. Thesis topics from production practices closely concern. Depth discussion of these issues and solutions for wind power grid to provide certain reference for practice , and China's wind power grid coordinated development play a catalytic role .
